No difference, viewing angles are still really good.... there really doesn't seem to be any negatives to it plus is stop finger prints getting all over the glossy screen.
I just bought a generic, no name Chinese one that is meant for an iPad from a small phone repair shop. It was AUD$19. I had a hard time finding any stores that sold any name brand versions.  
Measured the screen, cut it with a guillotine for straight edges and applied it. 

Andrew, I get what you are saying but maybe i had too much bias creep into what I wrote (I've ordered a bmpcc). My point is that between the two the features and price are different enough that each are targeting different audiences. There are plenty of people that think each camera is garbage and amazing. Personally, I didn't even consider the gh5s or gh5 because they are far more expensive. So even given the they have differences, I would have taken a hit on quality and features just for the sake of saving money.
